      Create Weight Table for ECMWF Grids
  
      .. note:: The grids are in the RAPIDpy package under
                the gis/lsm_grids folder.
  
      Parameters
      ----------
      in_ecmwf_nc: str
          Path to the ECMWF NetCDF grid.
      in_catchment_shapefile: str
          Path to the Catchment shapefile.
      river_id: str
          The name of the field with the river ID (Ex. 'DrainLnID' or 'LINKNO').
      in_connectivity_file: str
          The path to the RAPID connectivity file.
      out_weight_table: str
          The path to the output weight table file.
      area_id: str, optional
          The name of the field with the area of each catchment stored in meters
          squared. Default is it calculate the area.
      file_geodatabase: str, optional
          Path to the file geodatabase. If you use this option, in_drainage_line
          is the name of the stream network feature class.
          (WARNING: Not always stable with GDAL.)
